Increase Keptn Cert Manager coverage

[RealAnna]

Add unit tests to increase coverage of the cert-manager operator in Keptn. Specifically, improve coverage for the following files:

• [ ] watcher.go
• [ ] secret.go
• [ ] eventfilter.go

Ideally, code cov for the package should reach 70%.

Hello @RealAnna I have implemented unit test before can i work on this? as I am a new contributor also

[Bharadwajshivam28]

Just I have few small doubts that are-

1. There are already test written for the files you mentioned so do i need to modify it to increase coverage and how and where can i see the coverage %
2. Do i need to fulfill prerequisites to check coverage % ?
